Divers Corner:  Lessons for Life:   A diver feels unwell at depth   

Five minutes into the dive and at 50 fsw I started not feeling well. I was getting confused, nauseated and tunnel vision started. No matter how hard I inhaled I felt I was not getting enough gas (I was breathing nitrox).  I managed to get my breathing under control, ended the dive and made a controlled ascent to the surface with my instructor right beside me. During this dive I was taking a dive rescue course.

It took a lot of will power not to take my regulator out and bolt for the surface. There was nothing wrong with my gear or the quantity of gas, tank was fully on (we checked later). After surfacing, we returned to our villa and I was put on oxygen for an hour. I felt much better and cautiously returned to diving the next day.    

DAN Comment:  There are several possibilities to explain this diver suddenly feeling very unwell at depth. On further questioning, some of the possibilities were deemed less likely candidates but it appears that excess carbon dioxide (CO2) could not be ruled out, nor carbon monoxide (CO) or hydrocarbon poisoning. 

CO2 can be generated within a diver, such as by “skip breathing”, working excessively, using a regulator with a high breathing resistance, wearing too tight a wetsuit and/or a number of other mechanisms, or it can be delivered to a diver, for example in the tank, if it had been filled next to an engine exhaust, etc. Oxygen is not necessarily the recommended treatment for excess CO2, breathing air may just as effectively wash out the CO2, but it would not normally make the diver’s condition worse. 

Oxygen is the recommended treatment for CO poisoning though, which may present with similar symptoms. CO is not produced by divers and can only be introduced from an external source. The same applies to hydrocarbon poisoning, which may be introduced by the compressor used to fill a tank.  We may never know what caused this diver to suddenly feel unwell underwater but, regardless, he kept a cool head, ended the dive, made a controlled ascent, then sought treatment, recovered fully and resumed diving.

DAN is currently helping divers who think they may have experienced breathing gas contamination by supplying them with a breathing gas analysis test kit. If you have experienced an incident possibly related to breathing contaminated gas and have lawful control of the tank, please preserve your tank and contact DAN Research by phone (919-684-2948, ask for the Research department) during regular office hours (8:30am-5:00pm EST) or through the online incident reporting system.

Reminder: Did you know water robs the body of heat 25 times faster than air?Factors that accelerate the onset of hypothermia: ✔️Prolonged exposure to cold water temps. ✔️Sea spray.
✔️Air temp. ✔️Wind chill. ✔️Movement in cold water. ✔️Dehydration. ✔️Thin physique. ✔️Unprotected major heat loss areas.

1-10-1 is a simple way to remember the phases of cold-water immersion. You have 1 minute to control your breathing. You have 10 minutes of “meaningful movement”. You have 1 hour of consciousness, if wearing a life jacket! In the cold, conserving body heat is essential for survival.

Factors affecting survival time include: ✔️Protective wear, including a life jacket and insulated clothing. … .(Cotton robs the body of heat and should be avoided!) ✔️Ability to control breathing. ✔️Ability to stay calm and not panic. ✔️Will survive.

REMEMBER: ANYONE can call off a dive at any time. It is always OK to say “No
